There's actually no way to load balance between multiple ports. If there were, the config would probably have to be changed to something like host=127.0.0.1:3306 host=127.0.0.1:3307, because otherwise it would be confusing what should happen when there are multiple hosts and multiple ports. Anyway, maybe you could use multiple IPs instead of multiple ports? "host=127.0.0.1 host=127.0.0.2".

What I actually have is: connect = host=127.0.0.1 port=3306 dbname=users user=user password=pass connect = host=127.0.0.1 port=3307 dbname=users user=user password=pass two different port configurations (I'm running stunnel), rather than two different host entries[0]. >The right way would have been: > > connect = host=127.0.0.1 host=127.0.0.2 port=... So, if I just have two different ports, would the right way be: connect = host=127.0.0.1 port=3306 port=3307 dbname... ? micah 0. When I was anonymizing the db connection information in the original post, I accidentally changed the ip and decided it didn't matter for the question I was asking, so just left it. Now I see that might be confusing. pgpN0jQlsZCIa.pgp Description: PGP signature

If you actually have it like that, it should only be using 127.0.0.2, as the second connect setting overrides the first one..

You have two possibilities: a) Have doveadm use another auth-userdb socket that points to another dovecot installation with different configuration. b) Use a different userdb configuration for doveadm: protocol !doveadm { userdb { driver = sql args = /.../dovecot-sql.conf.ext } } protocol doveadm { userdb { driver = sql args = /.../dovecot-sql-slave.conf.ext } }
